Billy Hartwell and Anne Larsen are again the protagonists in this tale of Mexican drug cartels against a backdrop of the ancient cultures and treasures that still exist in many countries throughout Mesoamerica, including Mexico. The explosion of meth and fentanyl into America is an outrageous evil that is growing every day because those drugs are easy to make, and do not require any soil and water to grow, like marijuana, heroin, or cocaine. Plus, the cartels can buy inexpensive pill making machines which produce thousands of pills per hour that look like harmless prescription medicines, yet when shipped to the USA the profits to the cartels are worth billions. The death toll in America is skyrocketing because there are no controls on the contents of the pills and innocent young people are dying at an unheard-of rate. Billy is looking for treasure in the ancient ruins and Anne, a CIA agent, is working to stop the drug trafficking. Their work puts them in constant danger with their combined commitment to find treasure and save lives. The story also includes two incredibly talented Beagle dogs that help Billy maintain his reputation as the most famous treasure hunter in the world.
